ABSTRACT

Rassmatrivaetsya problema identifikacii tehnologicheskoy sistemy pri frezerovanii metodom operacionnogo modal'nogo analiza po izvestnomu signalu otklika na neizvestnoe vozbuzhdenie. Na pervom etape reshaetsya zadacha vyyavleniya sobstvennyh chastot dinamicheskoy sistemy metodom razlozheniya v chastotnoy oblasti matricy vzaimnoy spektral'noy plotnosti signalov. Na vtorom etape vychislyayutsya koefficienty otnositel'nogo dempfirovaniya. Predlozhennyy algoritm prodemonstrirovan na modeli dvuh svyazannyh oscillyatorov, a takzhe primenen dlya identifikacii real'noy tehnologicheskoy sistemy pri frezerovanii.
